Last year, Insane Clown Posse vowed they would march on Washington D.C. to protest the FBI, with whom they’ve sparred for the last few years. (In 2011, the FBI named the Juggalos a “loosely organized hybrid gang”; ICP sued the FBI over the slander in 2014, lost the initial lawsuit, and won on appeal in 2015.) Shaggy 2 Dope and Violent J are not ones to break their promises, and ICP have officially announced the Juggalo March, which will take place September 16 at Washington D.C.’s National Mall.

“This is the day that we are asking every single Juggalo to join us in our nation’s capital, Washington, D.C., to make a collective statement from the Juggalo Family to the world about what we are and what we are not,” the group said on a website launched for the march. “We must collectively show them that we truly are a family that is united by a shared love of music and fellowship.”

The march will be followed by a free concert with performances by ICP, Vanilla Ice, 2 Live Crew, and several other artists affiliated with ICP’s Psychopathic Records.

The website claims that ICP fans have been discriminated against for their fandom, owing to the FBI’s designation: “Over the past five years, our legal team has heard testimonies and reports from Juggalos all over the nation who have lost custody of their children, been fired from jobs, denied access into the armed forces, and the most common consequence — being officially labeled as a gang member by law enforcement agencies for wearing Juggalo related clothing or brandishing one or more Juggalo tattoos.” A page on the site also features similar testimonies from Juggalos.

The Women’s March, which took place over the weekend in cities across the world, was noted for its generally peaceful nature and complete lack of arrests in Washington D.C., which was partially attributed to the demographics. Put bluntly, the cops weren’t going to start busting the heads of so many well-meaning white people.

But how will the Juggalos be treated by local law enforcement, given their charged reputation amongst the intelligence community? The website notes that security will be on hand to make sure everything goes smoothly; it also emphasizes, quite heavily, that serious protesters only need apply.

The section about the protest reads as follows (emphasis theirs):

“This summer there will be an infomercial explaining to everyone about march/demonstration etiquette. To be sure, this is NOT a party, Gathering of the Juggalos, or a frivolous social event. This march is a serious, peaceful public demonstration, organized for one purpose — to deliver a message to the world showing how Juggalos have been unfairly stigmatized and discriminated against simply for identifying as being part of a particular music-based subculture. The golden rule of the march for participants is simply this: If you’re not serious about being there, just stay home.”
